The main reason is that I want everyone to thoroughly understand why it is usually said that the forwarding rate of Layer 3 switches is faster than that of routers. Let’s break it down into two sections: I did an experiment myself. The switch divided two vlans, namely vlan2 and vlan3. The two VLANs realize intercommunication through layer 3 switching, but I don’t know how to implement the two VLANs when connecting to the external network. Problem description: Requirement: The switch is divided into 3 vlans, all of which can access the external network, and vlan1 and vlan2 can communicate with each other. vlan3 cannot communicate with vlan1 and vlan3. How to configure routers and switches, please be as detailed as possible.
